The Company has granted options to employees, directors, and consultants under the 2015 Equity Incentive Plan (the "2015 Plan"). The 2015 Plan provides for the grant of incentive stock options ("ISOs"), nonstatutory stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance-based stock awards and other stock-based awards. Additionally, the 2015 Plan provides for the grant of performance-based cash awards. ISOs may be granted only to the Company's employees. All other awards may be granted to the Company's employees, including officers, and to non-employee directors and consultants. The 2015 Plan expired in accordance with its terms in January 2025 and was replaced by a stockholder approved plan in February 2026.

No stock options were granted during the three months ended March 31, 2026 and 2025.

The following table summarizes stock option activity for employees and non-employees for the three months ended March 31, 2026 and 2025:

Shares and weighted average exercise price have been recast to reflect the 1-for-15 and 1-for-12 reverse stock splits effected on August 15, 2025 and March 6, 2026, respectively.

As of March 31, 2026 and December 31, 2025, there was approximately $0.9 million and $1.1 million, respectively, of total unrecognized compensation cost related to unvested stock options. Total unrecognized compensation cost will be adjusted for future changes in employee and non-employee forfeitures, if any. The Company expects to recognize that cost over a remaining weighted-average period of 0.37 years.
